Maybe a 61 or 62.
From a post by Wade:
1961 – 1967 Kodiak Specials listed in Bear Catalogs
1961 – 63”, 66”, 69” – Soft Green glass, Zebrawood Riser
1962 – 63”, 66”, 69” – Soft Green glass, Brazilian Rosewood Riser
1963 – 63”, 66”, 69” – White glass, Rosewood Caps, Bubinga Riser, Shelf in front of Caps
1964 – 63”, 66”, 69” – White glass, Rosewood Caps, Bengal Wood Riser, Rounded Sight Window Corner
1965 – ……. 66”, 69” – White glass, Brazilian Rosewood Caps, Brazilian Bubinga Riser, Scalloped Sight Window
Just realized i can probably use my 1916's - just increase the tip to 200gr and that will reduce spine enough.
I love that calculator!
